CDMA mobile communication system, searcher circuit and communication method

A CDMA mobile communication system is capable reduce power consumption. A CDMA mobile communication device realizes a CDMA communication by combining outputs of finger circuits performing despreading for reception signals. The CDMA mobile communication device includes subtracted performing subtraction between delay profile data respectively output from at least two correlators respectively corresponding to reception signals transmitted from mutually different antennas, and assigning unit assigning the finger circuits for despreading reception signals to result of subtraction having signal level higher than and lower than a reference level so that outputs of the assigned finger circuits are combined.
